PURPOSE:To obtain a secondary radar information extracting device enabled to identify and maintain an aircraft and use altitude information at a C mode by using a comparatively simple device constitution. CONSTITUTION:A main decoder part 18 generates a parallel degarble code pulse 105 and a mode gate signal 104 from a code pulse 101 and a mode pulse 102 sent from an SSR transmitter/receiver and sends these pulse and signal to a subdecoder part 26. The subdecoder part 26 generates an SSR decoded video signal 111 from a discrimination mode code 110 sent from a control display device 27, a bearing angle signal 112 sent from an SSR antenna, trigger signal 113, and respective signals 104, 105; and the signal 111 is outputted to a display device 28. The display device 28 executes double slash display of an objective aircraft and outputs a displaying altitude information signal 109 to a control display device 27. |
